These items give 10 EVs to the appropriate stat instantly, but cannot take a stat over 100 EVs (regardless of how those EVs were obtained), so always use Vitamins first. Pokerus and Power items do not affect Vitamins. They're a good quick start to EV training, but given the 100-EV limit, they won't finish your training for you.

There are also Wing items that can be obtained more rarely. These add only 1 EV each (except the Pretty Wing, which doesn't do anything at all) but work up to the usual 252 limit instead of 100. Again, this is not boosted by any means.

And what of Super Training?

Super Training is a new mini-game you can play to increase your EVs.

The main training has you shoot soccer balls into a goal tended by a Pokemon-shaped balloon, while avoiding balls hitting your own goal. You start with level 1 training. A successful level 1 game will grant your Pokemon an instant 4 EVs in the stat you were training.

Once you've completed all six level 1 training sessions once, you open up level 2 training, which grants 8 EVs per game. Beat all of them to open level 3 training, for 12 EVs per game. After you max your EVs on a single Pokemon, you can play "Super Secret" training for items, but since this is a topic about stats, I'll not go into details on that here. Pokerus and Power items do not affect Super Training.

The higher your EVs, the easier the Super Training games are, and each stat boosts some aspect of your Pokemon's performance. Different Pokemon shoot the ball differently in Super Training (some charge the ball, and some shoot rapid-fire. It is generally agreed that rapid-fire Pokemon have a harder time winning.)

You also get punching bags for completing Super Training regimens, and also for having your Pokemon punch the default black bag on the Super Training screen. Some of these bags affect your EVs as well. Once you select a bag, your Pokemon will automatically punch it once per minute, or you can tap on the bag with your stylus rapidly to speed the process along. A small stat bag will grant 1 EV, a medium 4, and a large 12. There are also bags that influence how many EVs you get from Super Training, and Reset Bags, which I'll get to further down.

Any other ways to gain EVs?

The Juice Shoppe, on Lumiose City's Autumnal Avenue, can sell you drinks (or allow you to make your own by mixing two berries). The colored drinks (which can be made by mixing two berries of the same color) grant between 4 and 32 of a given EV.
